Ecumenical Patriarch Pyrros I

Ecumenical Patriarch Pyrros I (600-1 June 654) was the Ecumenical Patriarch of Constantinople from 638 to 641, succeeding Ecumenical Patriarch Sergios I and preceding Ecumenical Patriarch Pavlos II and in 654, succeeding Pavlos II and preceding Ecumenical Patriarch Petros.

Biography
Pyrros was a follower of Monothelitism, an ideology of Orthodox Christianity founded by Emperor Heraclius. In 638 he became the Patriarch, but in 641 he was accused of plotting against Constantine III of Byzantium, and the usurper Valentinus expelled Pyrros to North Africa. In 654, despite being excommunicated by Pope Theodore I for rejecting and returning to Monothelitism, he was made the patriarch for a year before his death.
